Figure 14 is a cross-sectional view of the teeth of the pet engageable portion shown inFigures 10-12 and is taken about the line 14-14 shown inFigure 13 . - A preferred embodiment of a pet grooming tool in accordance with the invention is shown in
Figures 1-5 and indicated byreference numeral 10. Thepet grooming tool 10 comprises a petengageable portion 12, ahandle portion 14, and agrip portion 16. - The pet
engageable portion 12 of thepet grooming tool 10 is formed of a polymeric material, preferably by using an injection molding process. Preferably but not necessarily, the polymeric material that forms the petengageable portion 12 is either polycarbonate or acetal, which have relatively high tensile yield strength and good creep resistance as compared to other less expensive polymeric materials. As shown most clearly inFigures 6-8 , the petengageable portion 12 preferably is generally rectangular in shape and preferably comprises a planarrear surface 18 and a parallelplanar front surface 20. Preferably, anarcuate surface 22 of the petengageable portion 12 extends down from thefront surface 20 and tapers therefrom toward therear surface 18. - A plurality of
teeth 24 are preferably formed in a row along the bottom of the petengageable portion 12. Eachtooth 24 is preferably bound in front by thearcuate surface 22, in the rear by therear surface 18 and, except for the first and last teeth in the row, by twotooth side surfaces 26. Anintersecting surface 28 is preferably formed between each adjacent pair of theteeth 24. Each intersectingsurface 28 is preferably planar and preferably extends from thearcuate surface 22 to therear surface 18 in a manner creating an acutehorizontal edge segment 30 with the rear surface. Eachedge segment 30 preferably has an edge angle of between forty-five degrees and seventy-five degrees, and more preferably of approximately sixty degrees. - The
tooth side surfaces 26 of eachtooth 24 acutely intersect the side tooth surfaces of each adjacent tooth at the root of the tooth. It is from such intersections that theintersecting surfaces 28 extend downward toward theedge segments 30. Thetooth side surfaces 26 of any giventooth 24, excluding the first and last teeth 36, also preferably acutely intersect each other at thetip 32 of said tooth in a manner forming an acute edge 34 that extends horizontally and generally perpendicular to theedge segments 30. Thetips 32 of the first and last teeth 36 in the row preferably do not have acute edges. Additionally, the first and last teeth 36 are preferably wider than the other teeth to reduce the likelihood of damaging the teeth in the event that the pet grooming tool is dropped. Preferably there are between thirteen and fourteen of theteeth 24 per inch along the row of teeth and preferably thetips 32 of the teeth are approximately an eighth of an inch below theedge segments 30 of thepet engageable portion 12. - The upper portion of the
pet engageable portion 12 may optionally comprise one ormore openings 38 or other indentations.Such openings 38 or indentations create cavities in thepet engageable portion 12 that allow thehandle portion 14 of thepet grooming tool 10 to be secured to the pet engageable portion via interlocking geometry, but are not necessary if the handle portion is melt bonded to the pet engageable portion. - After the
pet engageable portion 12 has been formed, it is preferably placed in another mold into which another polymeric material is injection molded to form thehandle portion 14. The polymeric material used to form thehandle portion 14 can be any one of commonly used engineering plastics such as ABS, nylon, and ploypropylene, and is preferably less expensive than the polymeric material used to form the pet engageable portion. Notably, the material used to form thehandle portion 14 needs not be as creep resistant nor have as high a yield strength as the material used to form thepet engageable portion 12. Preferably however, the polymeric material used to form thehandle portion 14 has a melt temperature close to that of the polymeric material used to form thepet engageable portion 12 such that the materials become melt-bonded to each other when the handle portion is formed. Alternatively, thepet engageable portion 12 can be provided with cavities, such as theopenings 38 shown inFigure 6 , so that thehandle portion 14 becomes geometrically interlocked with the pet engageable portion when formed therearound. - The mold used to form the
handle portion 14 is preferably shaped such that, when formed, the handle portion comprises abase portion 40 that encircles the upper portion of thepet engageable portion 12, and anelongate portion 42 extending therefrom. Theelongate portion 42 of thehandle portion 14 is preferably shaped to be grasped comfortably by hand. Additionally, theelongate portion 42 preferably comprises a plurality of recessedareas 44 and a through-hole 46 at its distal end. The through-hole is provided simply to provide means for hanging thepet grooming tool 10 from a hook or the like, and for provided means for attaching a lanyard to the pet grooming tool. - After forming the
handle portion 14 of thepet grooming tool 10, the assembly of thehandle portion 14 and thepet engageable portion 12 is then placed in yet another mold. This mold preferably has a shape similar to the mold used to form thehandle portion 14, except at areas where the recesses on the handle portion are located. This mold is configured so that yet another polymeric material, such as thermoplastic polyurethane, styrene-ethylene/butylene-styrene copolymer, copolyesters, copolyamides, thermoplastic rubber, or thermoplastic vulcanate, can be injected molded into the recessedareas 44 of thehandle portion 14 to form thegrip portion 16 of thepet grooming tool 10. Thegrip portion 16 preferably has an outer contour that meets flush with the outer contour of the handle portion adjacent the recessedareas 44. The polymeric material used to form thegrip portion 16 preferably is softer than the polymeric material used to form thehandle portion 14 and preferably has a higher coefficient of friction. As such, thegrip portion 16 increases the comfort and improves the grip when grasping thepet grooming tool 10. - The
pet grooming tool 10 is preferably utilized to remove loose hair from a furry pet, such as a dog or cat, without cutting or pulling non-loose hair from the pet. In use, a person grasps thehandle portion 14 of thepet grooming tool 10 and presses thepet engageable portion 12 of the tool into the fur of a pet. Preferably thepet grooming tool 10 is held in a manner such thatrear surface 18 of thepet engageable portion 12 is generally perpendicular to the skin of the furry pet. The pet grooming tool is then preferably pulled in a manner such that thefront surface 20 of thepet engageable portion 12 trials behind therear surface 18 of the pet engageable portion. As thepet grooming tool 10 is pulled, both loose and non-loose hair passes between theteeth 24 of thepet engageable portion 12. The acute angle ofedge segments 30 facilitates the ability of thepet engageable portion 12 to pull the loose hair from the pet without also cutting or pulling non-loose hair from the pet. Additionally, the acute shape of thetips 32 of theteeth 24 helps channel hair into the voids between theteeth 24, whereas blunter teeth would otherwise tend to mash hair against the skin of the pet. - An alternative pet
engageable portion 100 in accordance with the invention is shown inFigures 10-14 . This petengageable portion 100 is also preferably formed out of a plastic material and is adapted to be joined to a handle portion in a manner similar to that described above. The alternative petengageable portion 100 is preferably generally rectangular and comprises afront surface 102 and arear surface 104. Thefront surface 102 is preferably parallel to the rear surface and space about 0.136 inches therefrom. A plurality ofteeth 106 extend downward at the bottom of thepet engageable portion 100. Preferably there are between eighteen and twenty-twoteeth 106 per inch, and more preferably twenty per inch. Each tooth of an adjacent pair of teeth intersects the other at aroot 108. Each tooth become narrower as it extends downward and ultimately terminates at a rounded or otherwise bluntedtip 110. - As shown in
Figure 14 , theroots 108 are angled obliquely from therear surface 104 of thepet engageable portion 100 to form anedge 112 having an acute inside angle. This angle is preferably between thirty and fifty degrees, and more preferably between thirty-five and forty-five degrees, and still more preferably about forty degrees. As is also shown inFigure 14 , the lowermost surface of eachtooth tip 110 is also angled obliquely from therear surface 104 of thepet engageable portion 100.
